Of course, should have thought of that.

gmp has a two-stage system at the end. It generates two different .s
files, first it tries:
cc dummy-278371.s dummy-278372.c -o dummy
If that fails (which it does and looks similar to the mpir
config.guess output) it tries the other .s file:
cc dummy-278370.s dummy-278372.c -o dummy
which succeeds. Running the binary returns "core2". I will attach
both .s and the .c file for you to look at.
Jeff.
